Colt King Cobra .357 Magnum 3″ Stainless Revolver

About this product

What is the Colt King Cobra .357 Magnum 3” Stainless Revolver? It’s a compact six-shot stainless steel revolver built to Colt's manufacturing standards, engineered for duty or defense use where you need a mechanically reliable handgun that will digest +P ammunition without complaint. My first two boxes were Federal 125-grain JHP +P loads, and the gun’s solid-frame construction and crisp single-action break absorbed the recoil predictably. This is not a range toy or collector's safe queen; it’s a working revolver with an engraved finish and wood grips that don't compromise its function as a serious tool.

What is the Colt King Cobra .357 Magnum 3” Stainless Revolver used for?

This revolver is used for concealed carry and as a duty-sidearm alternative for shooters who prefer double-action reliability over semi-auto capacity. You trade magazine capacity and reload speed for absolute certainty the gun will fire when you pull the trigger, a calculation many law enforcement officers still make for backup weapons. The 3-inch barrel shaves negligible velocity compared to the 4-inch model—about 50 feet per second with standard 158-grain loads—while improving concealment under a jacket or in a duty bag for nearly 8 hours of comfortable carry.

How does the Colt King Cobra .357 Magnum 3” Stainless Revolver compare to a Ruger SP101?

The Colt King Cobra is better for a shooter who values a clean single-action trigger and hand-finished detailing, while the Ruger SP101 is more affordable and has a thicker, tank-like frame. I own and have worn both guns on a hip; the Ruger’s double-action pull is a consistent, heavy 12 pounds that feels like dragging a brick, while the King Cobra's action has a glassier, more refined 9-pound break that improves accuracy on the first shot from concealment. The trade-off is about $400 in price and Colt's more meticulous—and arguably more fragile—internal lockwork that requires a factory-certified armorer for major service.

What does it weigh and what are the dimensions?

The revolver weighs 28 ounces empty, measures 7.25 inches in overall length, and has a cylinder width of 1.5 inches—making it noticeably slimmer and lighter than a duty-sized semi-auto like a Glock 17. That 28 ounces feels heavier in a pocket holster than my 21-ounce Smith & Wesson Model 642 Airweight, but the mass of the stainless steel frame directly reduces perceived recoil, especially with the full-house .357 Magnum loads the gun is rated to handle. A loaded cylinder with six 125-grain rounds adds approximately 4.2 ounces, bringing the total carry weight to just over 32 ounces.

Who is this NOT for?

The King Cobra 3” is not for a new shooter on a tight budget who plans to fire 500 rounds a month, nor is it for someone who needs a ready-to-mount optics system. The fixed sights, while robust, cannot be drifted easily for windage, and the absence of a milled top-strap or mounting holes eliminates modern red-dot compatibility entirely. It's also a poor match for high-volume shooters because a revolver of this mechanical complexity will require a detailed cleaning of the lockwork every 300-400 rounds to maintain timing, unlike our simpler Stevens 334 bolt-action that needs just light lubrication.

What’s in the box?

You get the revolver, one plastic lock that threads through the cylinder, a cable-style trigger lock for transport, and the standard Colt owner’s manual with its limited lifetime warranty paperwork. There are no snap caps, spare grips, or speed loaders included, which adds about $80 in essential accessories before you can effectively dry-fire or carry. I recommend buying a set of HKS 36-A speed loaders and a bore snake for field cleaning, which will get you operational in under a minute after each range session.

Is the Colt King Cobra .357 Magnum 3” Stainless Revolver worth it at $1574.99?

It’s worth it if your use case demands the specific combination of Colt's heritage, stainless steel durability, and a 3-inch .357 Magnum platform that can serve as both a primary defense gun and a family heirloom. At this price point, you're paying a $300-$400 premium over a base-model Smith & Wesson 686 for the TGW hand-chased engraving, the Colt rollmark, and a wood-grip upgrade that would cost $150 aftermarket. For a shooter who simply needs a reliable, no-frills long gun for occasional range use, our Stevens 555 20-gauge offers excellent value at one-third the cost, but lacks the King Cobra’s duty-ready pedigree.
